About 20,000 homes in southern parts of the state are without power after another night of wet and windy weather.
In Perth, the areas hardest hit included Rockingham, Gosnells and Stirling including structural damage, water damage and roof damage. SES volunteers responded to about 50 calls for assistance.
Major structural damage has also been reported in Inglewood.
While Perth, Mandurah, Bunbury and Margaret River have seen the worst of the weather system, it continues to move across the state.
The Department of Fire and Emergency Services said people south of a line Walpole to Northam to Southern Cross to Norseman to Israelite Bay should take action and stay safe with the bad weather this morning.
This includes people in, near and between York, Southern Cross, Narrogin, Katanning, Albany and Esperance surrounding areas.
The cold front is likely to cause widespread dangerous winds in excess of 125 kilometres per hour that could result in significant damage or destruction to homes and property.
Dangerous winds are likely in this area this morning but conditions should ease by midday.
Higher than normal tides may cause flooding of low-lying coastal areas between Perth and Esperance.
Dangerous surf conditions are likely which could cause significant beach erosion.
The stormy weather is continuing to cause problems for the electricity network, with almost 20,000 customers without power in Perth and the South West.
Western Power crews have been working throughout the night to attend to faults on the network.
The South West is the worst affected area with more than 5000 customers without power in Manjimup and Bridgetown.
A helicopter will be deployed this morning to inspect the main transmission line which services the area.
If you see fallen powerlines remember to stay clear and call Western Power on 13 13 51.
